Local scale marine modelling of Fukushima releases. Assessment of water and sediment contamination and sensitivity to water circulation description

The dispersion of 137Cs released from Fukushima nuclear power plant to the sea after the March 11th 2011 tsunami has been studied using numerical models. The 3D dispersion model consists of an advec tion/diffusion equation with terms describing uptake/release reactions between water and seabed sedi...
